| 摘要: |
| 研究了磁性微粉的物相组成及其与聚乙烯相复合制成的吸波材料在8.2～12.4GHz 频段内的电磁特性。结果表明: 复合材料中聚乙烯的加入量对电磁特性在上述频段内各频率范围影响程度不同; 磁性微粉中聚碳硅烷量为20%时, 反射衰减大于6dB对应的频带宽度为2GHz。 |

| Abstract: |
| The composition and electromagnetic property of the electromagnetic wave absorbent prepared from magnetic fine powder and PE were studied. The result shows: the added amount of PE has different influence on the whole frequency range. When the added amount of polycarbonsilane is 20 percent, the reflection loss is more than 6dB, and the frequency width is 2 GHz respectivly. |
| Keywords: Fine powder, electromagnetic property, reflection loss |
